听力原文：M: Susan, do you know when Professor Jones' Biology Final is? W: Next Tuesday. M: Next Tuesday! That's less than a week away, and I have got things planned for this weekend. W: Haven't you been studying all along? M: I have kept up with my lecture notes, but I haven't reviewed at all. W: Then it's your own fault. The date of the final is clearly marked on the course outline. M: I suppose you are right, but doesn't it seem awfully early for a final? W: A little, but it should actually help us out. After we have finished with it, we can concentrate on our other finals. M: Are you ready for it? W: I think I am. I'm going to review some more of course. M: Do you think we could study together sometimes this week? W: I don't see why not. Are you doing anything tomorrow night? M: I can't tomorrow. I am going out with some guys to that new nightspot downtown. W: Well, how about the following night? M: No, I can't Saturday either. My sister and her husband are coming to town and I want to show them around. W: Sunday, then? M: Well, I'll probably sleep all morning and in the after- noon I want to go to the football game. Also that night I have to write and type up a paper for another class. W: Michael, that leaves Monday, the night before the test. M: Actually, I've got plans for Monday night too. How about Early Tuesday morning? W: Michael, the test is on Tuesday morning. (23)
